Range & Status
Always very localised in England, but has become very much scarcer in recent years.
Known from two old records: Porthgwarra (R.T. Bannister, 1963) and Marazion (1906).
Habitat & Ecology
The rarest of the four-spotted arboreal Dromius species; like the others, it is found on the trunk and branches of broadleaved trees and shrubs, and its rarity inexplicable at present.
The reasons for its extreme rarity are not understood and so it is impossible to suggest threats.
